>> but this cutting edge technology could be the answer >> the future of fracking is about the water >> protecting the planet, saving lives... >> how do you convince a big oil company to use this? techknow, only on al jazeera america this is al jazeera america. i'm thomas drayton in new york. let's get you caught up on the top stories of this hour - war leaders of wrapping up a g202-day economic summit in australia. climate change and russia and ukraine were high on the agenda. >> a doctor who contracted ebola in sierra leone has been airlasted to nebraska darren wilson is causing controversy - as the grand jury

decides whether or not to indict the officer in the death of michael brown da obama care's 2015 enrolment started today. we look at the affordable care act's future it's day two of the g20 summit in australia. russian president vladimir putin is leaving brisbane before the official ending of the summit. a spokesman said that was the plan and his departure, as you see, is not in response to tensions with other world leaders. on day 1 vladimir putin was condemned for russian support of separatists in ukraine. climate change made headlines with president obama urging leaders to commit to global warming. andrew thomas has the latest from brisbane. >> there are effectively two

agendas running in parallel at the g20. there's the official agenda. an overall way of increasing the side of the world economy by two percentage paints than predicted over the next five years. that will make a difference of $2 trillion for the size of the economy, creating 200 million jobs. that'll be the focus of the talks - how to achieve the 2% target, how to increase infrastructure. how to encourage trade liberalization, making sure the energy markets work. how the banking system is resilient to shocks. this will form the bulk of talks on sunday. when you have so many world leaders in one place at one time, other issues find their way on to, if you like, the unofficial agenda. president obama, in his g20 speech made climate change a big theme, much to the disappoint. of the australian government organising the g20, because they

didn't want climate change to feature. will climate change be mentioned in the communique on sunday. likewise the crisis in africa with ebola. that has been discussed between the world leaders, will it make it into the communique. there's the elephant in the room, or the vladimir putin in the room, the situation between russia and ukraine. russia's involvement in ukraine, russia's possible involvement in shooting down of malaysia airlines flight 17. all these things at the top of the world leaders' minds. when stephen harper, the canadian leader shook hands with vladimir putin, he said "get out of ukraine" - pretty undiplomatic language. will there be more? doubtful. that is economics. >> following a trilateral meeting, u.s., australia and japanese leaders called for

peaceful resolution for maritime disputes. it comes a day after president obama warned of the dangers of the outright conflict in asia. in a joint statement president obama, tony abbott and shinzo abe indicated peaceful resolution of maritime dispunts in accordance with international law. china has been displaying military hardware. the setting was the air show in the south of the country. among the war planes, china's stealth fighter. the military says it was a chance to mimic f 35 war planes. china correspondent adrian brown reports. >> reporter: china's government says it wants to ease regional tensions. this airshow offers a glimpse of the military hardware at beijing's disposal. should it be joined into conflict with a neighbouring country. president xi jinping says

innovation is essential to economic growth, including defense technology. these are mock missiles for use in training exercises. the manufacturer says that there has been strong from from pakistan and russia. another country is curious. >> americans. >> america too. >> i'm not sure if they are interested to buy our product. maybe they are interested that we have such product. >> reporter: and there was a lot of interest in this - the debut of china's stealth fighter, the j 31. the pentagon says it merely mimics technology used in the u.s.-made f22 and f 35 war planes. apart from the united states, no country spend more on defense than china, but its budget is a quarter of the u.s.'s. analysts say if china's present

rate of spending continues, the gap would narrow. this is how a league table listed top military spenders in 2013. china's defense budget rising by 8%. >> translation: china should spend more on the military. the chinese fighter planes are not as good as the russian once. >> yes, indeed, china has spend a lot on defense. they have not spend it in the right place, like on better jet engines. russia has a big presence here. actions imposed in moscow means that the air show is one of few international event where manufacturers can exhibit. few russians we approached wanted to talk. once the firstly could look forward to defense shows in russia and the united states.

>> not now. previously it was possible. >> reporter: now it's not possible. china is an important customer. this show offered glimpses of some of china's home-grown defense technology, that is transforming the world's biggest military. >> drown's al jazeera. australia may be keeping the u.s. from making a strong statement about climate change. that didn't stop the u.s. in japan from announcing 4.5 million from green climate funds. the press released it was making good on an effort to support greenhouse gas emissions. donations are announced by germany and france. the chairman of a joint chief of staff arrived in iraq. this is the first visit since the coalition began to launch air strikes against i.s.i.l.

the trip was not announced ahead of times. he there to meet officials to discuss the advancing u.s. military operation. progress is being made against i.s.i.l., but he says the fight may take year. >> in the capital city, 15 were killed in a car bomb, 30 others injured. leaders meet in iraq. the coalition continues its assault in i.s.i.l. against neighbouring syria. u.s. forces carried out 20 air strikes, 17 around the border town of kobani. there has been fighting over the town for the past two months. u.s. forces struck an i.s.i.l. training camp in the area, and attacked a group outside of aleppo. >> an al qaeda-linked group is making gains in syria. the al nusra front is accused of seizing territory from moderates in what is viewed was a power grab. al-nusra fighters have a different take on the mission. >> ronald musagala has been a

powerful player in the syrian civil war for a long time as al qaeda's affiliated syria, it is the dominant group in the north western province of idlib. it seized territory and weapons from rebel forces in the area. that raised concerns, that al nusra front's strategy is to become the unrivalled leader among opposition forces. the group's leadership denied the take over was a power grab. we were told this was a war against corrupt leaders, who use weapons to oppress people. >> look at what is happening. other areas. we tight alongside other forces. our rein is not for everyone. we fight groups that act like jamal maarouf. >> reporter: jamal maarouf is a controversial figure who has been accused of corruption, he's

not the handle one, the hassan movement has been targeted. they are both backed by the united states government. >> at the moment in the north, nusra seems more worried about american-backed rebels, and the american-led international coalition - will it continue to confront rebel groups with whom it has been working. it's difficult to say. >> it's a critical time. the u.s. insists the air strikes targeted the group and not al nusra. but on the ground the feeling could not be more different. both groups share the same territory. the fighters that belong to al nusra front feel threatened. their group is threatened as a terror organization by the u.s. their vision for a new syria is not accepted by all. >> what we are planning for islamic law to be implemented. we don't want to be the only rulers, we share power with

other factions. >> there are no plans that the coalition will widen its campaign. al nusra feels it has been targeted. it's not clear if the offensive in idlib is part of a strategy. what is clear is that the group managed to get rid of enemies on the ground. >> it takes bullets to fight a war and funny to buy the bullets. that's the reality that led i.s.i.l. to use captured oil to found the war machine. nick schifrin got a look at the process. >> down a bumpy turkish road a few feet from the border, we set out to look at i.s.i.l.'s source of income. our guide - a 22-year-old female smuggler. her tools, jerry can ear marked for oil. in a discrete hotel room, we she how i.s.i.l. recruits. our recruiter is a 27-year-old it expert. his tools, keyboard and mouse,

as opposed to facebook and twitter. and on the require in istanbul, over a cup of tea... ..we learn how i.s.i.l. is organised. our expert, a syrian employed as an i.s.i.l. salesman. >> how did you recognise it? >> i.s.i.l. took over factories. they needed civilians who were not connected to them. i helped to sell the products. >> three people who demanded anonymity shows how i.s.i.l.'s management, organization and wealth are dependent on foot soldiers whose main motivation was income. they worked for an islamic state that may claim to nigh the flag of islam, but at whose heart is corporate. every aspect of the organization is structured. the smuggling that we saw a bit of right there, that is structured through its own hierarchy. the twitter and facebook that you saw of one of those men right there, that has its own

hierarchy, structure and sophistication. the videos are incredibly well put together and successful at continuing to recruit more and more foreign fighters allowing i.s.i.s. to be more victorious. this shows how difficult it will be to defeat i.s.i.s., and how pervasive, how far flung the foot soldiers are. so many people i have meat over the last month talk about i.s.i.l. members, not the fighters we see on tv, not the people who are ruthless and barr bar uk. that is the public fizz of i.s.i.l. the heart is civilians and people joining for any other reason. they are not true believers at all. without those people, without a legion of civilians, i.s.i.l. would not have had the successes that it has had. >> nick schifrin in jerusalem back at home, the family of

ferguson, missouri teenager michael brown issued a statement condemning the police department's release of audio and video. the man accused of killing brown, darren wilson - there was a video showing him leaving the police station headed to a hospital, two hours after the shooting. he returns two hours later. the post has audio tapes of a dispatcher talking about a suspect who robbed a video store, it is believed to be brown. the family statement says: a family statement released today. tensions are high in ferguson, where the community awaits of grand jury's decision

on whether to indict officer wilson, there's concern it could lead to violence, in response, groups are organising people on their rights. >> reporter: police advance on protesters, the intention is intimidation. the protesters on the ground link arms and whisper words of love into the officer's ears, love, love, love. >> holding each other in deep abiding love. not real is a lesson on how to protest tactics in a peaceful manner. unless there's violence. >> black lives have not mattered. it's very important that the friends of our struggle see themselves not only as allies, but as freedom fighters themselves. >> this is about a rotten system. >> reporter: gatherings like this have been held all week. thou protest peacefully in the face of what one here considers to be heavy-handed if not brutal

tactics, such as these seen in mid-august. such as the death of unarmed black teenager. >> there's somewhere between 70 and 100 members of the public. according to the organizers, they are following in the tradition of martin luther king. by training for nonviolent civil disobedience. >> what is it that these people hope to achieve by attending the session. >> i expect to be brushed up on nonviolent strategies that i, you know, over the years, and it's been a few years since i had to use 'em. >> we want to keep this in a loving atmosphere. people or places. >> or to get dragged into it. >> or get dragged into it. >> no one knows what the grand jury's decision will be, when it will come down, or if there'll be violent protests like last

summer a nebraska medical center admitted its third ebola patient, dr martin salia. he arrived in omaha after contracting it in sierra leone. his condition was described as critical. >> we received word from both medical teams on the ground in sierra leone, and the flight crew transporting him that he is extremely ill, possibly more ill than the patients transported from western africa to the united states to be treated for ebola up to this point. >> 44-year-old salia is a native of sierra leone, but is a permanent resident of the u.s. his family is grateful for the care. >> he is a hero to me. from when i was little, he brought me up to the kind of men we are, and makes sure that if i don't do the medical works, i'll do something that will make people happy, or feel like they have somebody they can look up to.

>> the center for disease control and prevention released new ebola numbers, liberia has the most cases of ebola with 6800. sierra leone has 5500, and guinea 2,000 cases. in the congo, however, the government declared its outbreak over. they have gone 42 days without recording a new case of the disease. 49 people died in afghanistan can countries during the outbreak there. some of the biggest names in the music industry started to record a song to raise money for ebola research and treatment. bono and others gathered at a studio in london. they are recording a new version of band-aid single "do they know it's christmas." the song will be released on monday and the proceeds will go to the fight against ebola. band-aid was a super group in the '80s. a group of singers in west africa released a song about

ebola, in an attempt to clear up information about the virus, and to inspire hope. [ singing ] singers from mali, guinea, senegal, ivory coast and the congo led their voice to the project, sung in french. they sing that ebola is the invisible enemy, trust officials and not be ashamed to get treatment. >> four were killed in a texas chemical plant leek. it happened at a dubawnt industrial -- dooupant plant. a chemical used to create insecticides and fungicides leaked around 4:00am this morning. several workers were exposed to the chemical. one is hospitalized. >> today we lost four of our family members from the site. we had the incident this morning, revoting in exposure of five employees, four of which

were fatally exposed. the fifth is in the hospital, expected to make a full recovery. merely for observations. >> the sp says the surrounding -- company says the surrounding company was not at risk and the airways safe. >> as it left the site and was in the air, it dissipated to an amount where it was not hazardous. monitoring was done, and the local response agency made the decision that there was no health hazard to the community as the odour left the site. >> the leak happened at 4 o'clock this morning, a faulty valve to blame after last year's disastrous rollout, the white house is promising a better experience with obama care 2.0. coming up we look at the start of enrolment in the future of the affordable care act. plus, the senate is expected to take up a keystone pipeline next week. we examine the physics of petroleum transport. plus, president obama is

considering executive action to push forward his immigration reform agenda. still ahead - we speak with a man racing against time to stay with his family.

welcome back, today is the first day of the 2015 enrolment of obama care. criticism remains strong as ever and the future is that much more uncertain. here is jonathan betz with a check-up on the affordable care act. >> reporter: as open enrolment begins for 2015, new secretary of health and human service, silvia matthew barwell is promising a smoother ride navigating health care.cove.

-- healthcare.gov. >> things are simpler. >> reporter: it's been reported that there were problems with the back end site, and nevada and oregon abandoned state-run site. leaving 13 states operating their own exchanges. >> if you have not signed up for insurance. this is your chance. the white house tries to enrol 7.1 million people in the marketplace. adding millions more for 2015. more people are expected to sign up for medicaid. federal officials say 8.7 million americans were covered under medicaid. the children's health insurance programme, thanks to the 27 states that expanded the programs. >> there are 27 health insurers selling in the marketplace. up 25% from last year. why not, considering the industry has seen a boon.

the s&p 500 health care comprised of insurers, health care and others outperformed stocks. the department of health and human services say hospitals will save $5.7 billion thanks to an increase of insured patients. the house of representatives tried 47 times to repeal the affordable care act, and won't stop there. >> the house, i am sure, at some point next year will move to repeal obama care. >> when a republican controlled senate takes office. they'll likely vote to repeal. they'll need to muster 60 votes to avoid a filibuster and there's the power of the president's veto. repeal of the law i will not sign. efforts that would take away health care from the 10 million people who have it, and the millions more eligible to get it we are not going to support. >> if the affordable care act

survives congress in 2015, it will have to contend with the supreme court again. in 2012 the court upheld the report's individual mandate. this year it struck down a requirement for religious employers to take on loopholes. it could make health care unaffordable to many first day of open enrolment, the department of health and human services reported 23,000 submitted applications in the first eight hours. to talk about the affordable care act, let's welcome the chief operating officer of metro plus health plan, and a fellow director from the center of medical progress. good to have you with us. 23,000 in the firstate hours, is that good - thumbs up, thumbs down? >> it's good, great traffic. healthcare.gov is up and running. some states went down.

we should give it time before passing judgment. >> what have we learnt in the first year? >> today was a strong day. we benefitted from the experience of last year. all of us that went through it know there may be hiccups initially, but we are better able to anticipate what they are, to reach people who need insurance, able to explain the product, the infrastructure is more stable. a better position. metro plus had a strong day. we visited locations. we are point of view going in to the enrolment period. >> has the obama administration done a good job with obama care 2.0. >> i think the best thing they have done is set a low bar for expectations. when they issued estimates below c.b.o. 13 million are expected to sign up in 2015. the obama care has pulled it down to between 9-10 million. it's a great management tactic.

if they overshoot it - let's break this down. what has happened to premiums for 2015. >> the premiums overall had a small increase in new york. very modest. for any individual, the dollar value of that increase may be smaller than expected. with the subsidies available, they bring the dollar value down, it's a modest increase. >> what are we talking about - 3-4%. >> the average in new york was 5%. there was an increase over last year. there are plans that are cheaper. metro plus, which had the best membership in new york city, the most enrolled, we expect to have a strong year, and we think it's a response to having competitive products and a good experience for the consumers, and an association with the new york city health and hospital association, the leading public health entity in the country.

>> it was a smooth start in new york. will we seed a wider variety of doctors. >> i don't think we'll see to this year. it will take a while for consumers to hit across the country. i'm not sure how much wider the networks will be, or the positions. there's so much room to compete on price when you are constrained by the regulations. if insurance around the country wants to continue to compete. they have to keep the network constraineded. >> what does it mean for the patient? >> the insured needs to be better versed at looking at physicians, browsing through formulas. it's a learning process. >> what is the most confusing thing about the website. >> i don't know that it's confusing. >> it's 75,000 down to 16. >> new york didn't have a complicated role out in the website as nationally. they've taken steps. the confusion in consumers' mind

is all he noise that goes on around obama care. will it be here in the next year. will it go away or are the subsidies going away. we believe the law is here to stay and people should enrol. someone who is concern beside that and doesn't follow it, republican efforts to repeal it about discussions about subsidies, they may be confused as to what the next step is. if you enrolled last year, what did you do. >> if you enrolled last year, and you are happy and make no changes, you can do nothing and reenrol for the next year. we provide sa good service, and we'll continue to stay with us. others that have changes should go in, because based on income and family size, they may be eligible for greater subsidies. the overwhelming majority of people have strong experiences and will reenrol. >> will we see states expand

medicaid. >> i think little by little they'll find ways to work with the administration. it will be a bit more flexible. states want to the expand insurance especially to the population left out of the main expansion. they want to expand to poorer residents, so the administration will give space and a little bit. the money is enticing and that will pull in a lot of governors. >> let's talk about the young adults. what incentive do they have to enrol. >> we did well last year. 50% of the population that enrolled was under 35. which was a surprise to some people. some of that was just the publicity around the law, the desire, somebody - maybe someone's mum telling them you got to get insurance. this helps me, we like mums doing that too. a lot of young people are uncertain.

they are also not sure about insurance in general. it's something that you pay. you don't always see the benefit. part of our effort is to show people, that it is something you need no matter what. that is creating the environment that obama care is here to stay, that the affordable care act is going to be part of people's support. so some of the noise around that is not helpful. >> let's talk about that. is obama care here to stay? we have seen a shift in power in washington. your thoughts? >> i think it's here to stay. the law itself has no chance of getting repealed. the earliest that it will be possible is 2017. let's say you have 15-20 million insured through the law. no one will take away insurance from all those people. it is possible. that's what 2015, 2016 can bring with the republican congress and the democratic president. >> can we see parts of it chipped away.

>> we may see some of it, new york has a different structure, it operates its own exchange, and has strong laws and did expand medicaid, for example, significantly before. that's not a substantial risk in new york, but the national picture is a problem if the subsidies that go away, a lot of the inner working with the law do, are at risk of falling apart. while the law is strong, it provided great advantages to team. people. congressional action is less of a risk. it gets to the heart of the subsidies. >> what can health insurance companies expect in 2015. >> 2015 is hard to predict. most do not have the full year of experience. especially some of the new ones, new york, oscar insurance, they picked up a good number of people. some of them don't know what the full risks looks like, they

don't know who is healthy, who is sick. after 2015 or 2017, the federal buck stops, they'll be the trying years, that's when we'll have to look to see if obama care will stand on their open two feet. >> have they benefitted, the insurance companies? >> yes. they have created a market, given people the availability to purchase insurance. there's financial risk because of the nature of the market, who the customer is going be is uncertain. we a strong year in new york. 100 million enrolled state wide. the affordable care act. metro city. 45,000 enrolled. half of them younger people. the demographics is favourable. we look forward to it continuing. it gets harder as we go into another year. you are appealing to people with a level of uncertainty. we are not sure if insurance will be eligible.

you'll have to do a deeper dive into the marketing. we look forward to a strong year, we have a competitive product. and people at the end of the day understand the value of insurance for them and their families. >> we understand and you have some that can't afford it. what type of financial assistance is there. >> there's two types of subsidies that help with premiums. you get something called cost-sharing subsidies if you meet the threshold that help with pocket causes. a lot of people focus on the premiums, people pick the low plan, and they get stuck with high deductibles, and with wages slow, not picking up, it will be a big burden, they have to balance out the cautions and subsidies that are available, taking advantage of the consumer products. >> we have a longer enrolment

period, if you miss the deadline, what then. if you have a qualifying event. birth of a child, change of job, you move, you can enrol. for most people, this is it. for insurance companies, this is a super bowl. we have to be ready, we have been gearing up for months, we started out with bigger event to get people excited. we are confident we'll see a lot of people coming out. the initial traffic to the office indicates there's a lot of interest that people are aware in a way that you are not sure they will be. they may not always buy, they may be window shopping. >> is there advice of those shopping around. >> looking at it, if you are unsure, if you thing the price is too high, take a look. >> the final moments, what is the future of the law. what is in store. >> it's a broad question. >> if you think, some changes are definitely going to happen.

the medical device tax has a chance of going. the mandate may end up going, you need a lot of revenue to take up for that. other than that, it will depend on the administration, accepting flexibility, there's smaller parts of the law that may come and go. overall, it's here to stay. that's pretty much it. >> final thoughts? >> yes, i think it's a great benefit for people. i ran the new york city welfare programme for 15 years before taking this job. and the number one concern about people doing to work is the availability of health insurance. the insurance is giving people the ability to have health insurance. helping people live better lives, comfortable lives. it's important for our country to have health insurance. >> it will be a lot easier. >> thank you both, great to have

you with us on "a deeper look." despite a generally smooth start to affordable care act's open enrol. not everyone had a glitch-free experience. washington state health exchange had to shut down because of problems with tax credit calculations. officials and software engineers are working how to resolve the issue, it's not clear when the site will be back up and running. still ahead - we talk with a man who developed 480 varieties of wheat, and is helping to feed people across the globe. plus... >> i have lived day to day with anguish. >>..the struggle of illegal immigrants waiting to see if the president will take executive action on immigration.

video of an attack an on egyptian army that killed 30

soldiers has been posted online. the group that carried out the raid is an ally of islamic state of iraq and levant. and have threatened to carry out more attacks unless the military stops its campaign. >> reporter: in a half-hour long video posted on the internet. the group showcased its latest triumph. al jazeera cannot independently verify, but it showed the attack on the sinai. it killed 30 soldiers. the video showed the fighters, shooting them in the back of the head. it was accompanied by a 7-minute long message from a group's leader. which since won allegiance to i.s.i.l. it means the state of sinai. >> translation: we have warned you time and again, but you do

the access they need. they don't need a combined harvest. they need good seed. once a seed is discovered, some of the colleagues go out to meet farmers and train them to exploit the new verties as best they can. >> you can have the best seed, but if you don't have a farmer that nose how to put it into a working sustain -- that knows how to but it into a working sustainable system, you won't get that. >> reporter: scientists follow in his footsteps and work on developing new varieties, and testing ones in the field. a break through is the development of smaller and stronger wheat that doesn't saw down easily, so is productive. the challenge is greater, producing wheat to withstand extreme weather.

>> a challenge that the world is ready to take on it took weeks for authorities in pennsylvania to track down a man accused of shooting two state troopers. next on al jazeera america, the eye-popping price tag for the search, and who is going to pay plus, what is done to save the mission of the comet probe we'll tell you what is on top for fans at the packers' game, and assist an n.f.l. first.

and children since. his baby son is a u.s. citizens. that's why he's vowed to do everything in his power to stay. including suing the government agency tasked with saving him. together with a nonprofit group, luis filed a lawsuit for failing to respond to a petition in february. >> reporter: it's not too plate for him to take executive action, the president, to stay the exportation of people like luis. last week president obama admitted his policies needed review. >> we are (porting people that shouldn't be deported. >> we have here a public trial. >> immigrants rights activists say that the president could change that now. >> he could have done that yesterday, a year ago. there's no excuse why we should deal with the injury, the harm,

>> immigration is not the only major battle brewing. the keystone pipeline is about to hit the floor. on one side supporters say it will create thousands of jobs. the environment it important. jacob ward brings us the science. >> reporter: experts say the pipeline is the safest way to transport petroleum products from one place to another. the problem is you can't be everywhere. it is worse the more you lay. we are talking about a pipeline that will be newly constructed and join an existing pipe hin as it makes its way to the gulf of mexico. a leak can spread along the lines. the company that maintained pipelines created high-tech systems for monitoring their systems. in theory, they can spot leaks from a great distance, using

what goes in or outside the pipes. when small leaks take place, they can let a lot of oil go. >> a "wall street journal" report discovered in 251 leeks, only in 19% of cases was the pipeline monitoring technology the first to discover the leak. it was usually someone that happened to be in the area. in one case in september 2013, the farmer used his nose to discovered crude leaking into his wheat field and when the company came out and dug, they discovered 20,000 barrels of oil had been seeping into the ground. that leak, the fact that it was not detected by the pipeline system, it makes environmentalists nervous about laying the pipeline across the united states. the reason that we are concerned about oil, is it gets into the

body and cannot be expelled when human being and others absorb oil. they cannot get rid of it. it was passed up the food chain to larger predators. as it dice, it's passed into plants and fungi. one drop of oil can contaminate a million drops of oil. one gallon of oil. one million gallons of water. that's why everyone is so concerned about the pipeline. >> the controversy surrounding the keystone pipeline is the subject of sunday adds "the week ahead". -- sunday's "the week ahead". we'll look at both sides of the issue, while the passion for it is as strong as the arguments against it. remember the probe that landed on a comet on wednesday. apparently it ran out of power.

the robot lander was built with solar panels. shortly after touchdown, it has been in the shadows. when it touched down small harpoons attached to the legs should have fired and anchored the lander. they didn't work, it bounced not once, but twice, and balancing on two of three legs in a location heavily shaded from the sun. >> we are in the shadow of a cliff. that's as you understand parts of the problem. >> the lander was designed to get 6-7 hours of sunlight. it got less than that, 80 minutes on one of the three solar panels. mission controllers proceeding with the plan, activating a drill to cut into the surface, and manoeuvred the lander into a new position they hope will receive more light and restore power from landing a spacecraft on

a speeding comet to self-serve beer at football games. the green bay packers, the team that won america's first ever super bowl is the first to let the fans get their own beer. all you need is a $20 access card, and you go to the beer station, and you fill up. don't spill it like that fan. that'll do it for us for this hour. thank you for joining us, i'm thomas drayton in new york.
